1- Speak a little English every day:
The absolute best way to learn any new language is just to speak it. It doesn't matter if you only know five English words or if you're practically fluent -- speaking English with another person is the fastest, most effective method of improving.
Don't wait until you "feel more comfortable" speaking in English -- you probably won't reach that level for a long time, so push yourself outside of your comfort zone and start speaking English today. You' ll be amazed at how quickly your language skills improve.
2- Work on your pronunciation:
Even if you have an acceptable grasp of the English language, with good grammar and an extensive vocabulary, native English speakers may find you very difficult to understand if you don't work on your pronunciation.
Correct, clear pronunciation is essential if you really want to improve your level of English. Listen closely to how native English speakers pronounce certain words and sounds and do your best to copy them.
3- Expand your vocabulary and use idiomatic phrases:
The wider your vocabulary and the more English phrases you learn, the easier speaking English will become.
Again, spending time with native English speakers will help you to pick up on common vocabulary and phrases in a natural way. Although reading, watching English TV and listening to the news is also beneficial.
4- Attend an English class or discussion group:
Another great way to incorporate some extra English conversation into your weekly routine is to sign up for a class of discussion group.
Attending an English class is a great way to focus on some of the more formal aspects of speaking English. A class will teach you the grammatically correct way of speaking -- which includes proper sentence structure and verb conjugation and will generally provide a very structured approach to language learning.
5- Carry a dictionary:
Carrying an English dictionary with you at all times (whether it's an actual book or a phone app) can be very useful.
Having a dictionary means that you will never be stuck for a word. It can save you a lot of embarrassment if you're having a conversation with an English-speaker and forget a word in the middle of the sentence -- all you have to do is take a second to look it up!
